The first step in learning how to clean the air conditioner coils is by turning off the main power switch to the unit. The evaporator cover will be located near the fan on the unit.

The cover will be held in place with metal screws. Remove these with a socket wrench. Peel any metal foil tape along the edges of the panel.

To Clean Air Conditioner CoilsInspect the coils and fins to see if they are within reach. If so, fill a bucket with warm soapy water and wipe the coils clean. You can also purchase a can of air conditioner evaporator coil cleaner from your local hardware store. Do not use harsh chemicals or cleaners that could damage your AC unit.

Also, lay down a plastic drop cloth if the fan motor is beneath the coils for protection.

After you have tried wiping the coils clean, if there is still mold and other debris left behind, you may have to call a professional to have the coils steam cleaned with a solvent-based cleaner.

If you are cleaning the coils with spray cleaner, spray the foam directly onto the coils until they are completely covered. The foam does not need to be rinsed off. After a few minutes, the foam will liquefy. Turn your AC unit back on and allow the condensate water to rinse the coils.

While you have the cover off, you may want to pour an equal mixture of bleach and water into you drain pan to help keep the drain line clean. Replace the access panel and tape.
